This blackbird closely resembles its near-relative, the Red-winged Blackbird, but males sport white edgings, rather than yellow, on their flashy red wing epaulets. It is nearly endemic to California, where over 95 percent of the global population breeds, mainly in the Central Valley and other points west.
Tricolored Blackbirds form the largest colonies of any North American land bird, with a single breeding colony often numbering tens of thousands of birds. Like the Passenger Pigeon, the colonial nature of the Tricolored Blackbird makes it particularly vulnerable to extinction.
